Hi Jeff, Thanks very much for this. That all makes sense. The bike is a 2014 Honda and so would have run at the 2015 or 2016 TT. The sticker number is 215018 as far as I can make out, and has the TT logo above the number. The writing is black on a silver background. I've not worked out how to post a photo on this forum but can email it to you if that helps. 

Thanks for your help Jeff.

Best regards,


Gareth
